NICHOLAS H. BORGFELDT, OF NEW YORK, N. Y.

MACHINE FOR CUTTING TOBACCO.

SPECIFICATION forming part of Letters Patent N 0. 238,755, dated. March 15, 1881.

Application filed October 12, 1880.

T 0 all whom it may concern:

Be it known that I, NICHOLAS H. Bone.- FELDT, of New York, in the county and State of New York, have invented a new and 1mproved Machine for Outtin g Tobacco, of which the following is a specification.

.This invention relates to certain improvements on the tobacco-cutting machine which is described in Letters Patent No. 138,606, dated May 6, 1.873.

Theinvention consists in placing a hopping chute beneath the sieve-bottom of the feedbox for the purpose of receiving the small particles of tobacco from the feed-box, which need not be out, and impurities.

In the accompanying drawings, Figure 1 is a top View; Fig. 2, a side elevation Fig. 3, a vertical central section of my improved tobacco-cutting machine.

The letter A represents the frame of the machine.

B and O are the cutting-rollers, each of which is provided with a series of cutting-edges, a, and intervening grooves, b, the cutting-edges of one roller being set up against those of the other by a set-screw, D, or by a spring or weighted lever- Rotary motion is imparted to the rollers B and 0 by toothed wheels (I and e, as shown in Fig. 1. The Wheel 01 on one of the rollers is somewhat smaller than the wheel 0 on the other of said rollers, as indicated in Fig. 2. By this means the speed of the two rollers when they are revolved is not alike, and their cutting-edges a grind each other sharp by thus turning with different speed in contact with each other.

Into the frame A are set a series of small pins, f, which enter the grooves 11 of the rollers B and G, and serve as clearers. By having each of these pins'f independent of each other their independent adjustmentis rendered pos sible.

(N0 model.)

E is a feed-box, into which the tobacco is placed before it is moved, by hand or otherwise, to the rollers. Part of the bottom of this teed-box contains a sieve, g, through which the smaller particles of tobacco that are not to be out drop down into a chute, F, which is suspended below the sieve g of the feed-box. The chute F receives vibratory motion by being suspended by a hook, it, from a prismatic or cam shaft, 1'. The chute F may have a sieve,

j,forits bottom,for discharging through it the finest particles of tobacco or impurities, and carry along its face the less-fine particles of tobacco, which may be mixed with the cut portions that are also dropped into the chute from the rollers B and 0. By this means the requisite separation of the impurities, and also of the very tine particles of tobacco, from the remainder is automatically et't'ected.

Although I have described this as a machine for cutting tobacco, it may with equal advantage be used for cutting and separating other substances than tobaccosuch as herbs used for medicinal purposes, and the like.

I claim 1. In a tobacco-cutting machine, the stationary feed-box E, having stationary sievebottom g, in combination with a hopping chute F, which extends under the fixed sieve portion of the feed-box, substantially as described.

2. The combination of the cutting-rollers B G with the feed-box E, having sieve bottom g, and with the hopping chute F, having sievebottom j, that extends under the sieve-bottom g and under the cutting-rollers B and 0, substantially as described.
